function javafigurequeue(flag)
%JAVAFIGUREQUEUE Changes how Java Figures behave in regarding to whether
%using SwingUtilities directly and/or creating Java Figures asynchronously.
%   JAVAFIGUREQUEUE(FLAG) 
%
%  FLAG is an integer whose value can be empty or is one of the following.
%       0: Using Java Figure queue instead of SwingUtilities'.
%          Creating Java Figures asynchronously. This is the default.
%       1: Using Java Figure queue instead of SwingUtilities'.
%          Creating Java Figures synchronously.
%       2: Using SwingUtilities' invokeLater.
%          Creating Java Figures asynchronously.
%       3: Using SwingUtilities' invokeLater.
%          Creating Java Figures synchronously.
